Abstract

The present invention discloses an optical imaging lens. The optical imaging lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens which are sequentially distributed along an optical axis from an object side to an image side; the first lens has positive focal power, the object side surface and image side surface of the first lens are convex surfaces; the second lens has negative focal power; the third lens has negative focal power, and the image side surface of the third lens is a concave surface; and the fourth lens has focal power; the fifth lens has focal power, and the image side surface of the fifth lens is a convex surface; and the sixth lens has focal power, and the object side surface of the sixth lens is a concave surface. The maximum half field of view (HFOV) of the optical imaging lens is smaller than 30 degrees.

Description

technical field [0001] The present application relates to an optical imaging lens, and more specifically, the present application relates to an optical imaging lens including six lenses. Background technique [0002] With the rapid development of portable electronic products such as smart phones, people hope that the use of portable electronic devices can meet the demand for shooting distant scenes in the wild, and can achieve the effect of highlighting the subject and blurring the background. This requires that the lens not only has telephoto characteristics, but also has miniaturization characteristics and high imaging quality. However, the existing telephoto lenses usually increase the number of lenses to achieve high imaging quality, so the size is relatively large, and cannot meet the requirements of telephoto, miniaturization and high imaging quality at the same time. Contents of the invention [0003] The present application provides an optical imaging lens that is...
